Here’s how it works: on the back (or bottom, depending how you look at it) of your Cache are two parallel “rails” of 1″ wide, lightweight nylon webbing which extend from the top to the bottom.

Included with your Cache are what we call “Gatekeeper Clips”. (If you ordered your Cache before we included Gatekeeper Clips with the Cache, it’s necessary to order a pair from our Parts page should you choose to secure the Cache inside one of our larger bags via the rails system.)

Here’s how to operate the Gatekeeper Clips:
Squeeze the black part of the Gatekeeper Rail Clip together and flip up the rectangular metal bar to unlock the clip. Slip the open clip through the ribbon on the back of the Cache and flip the metal bar shut over the top of the clip. Repeat for the other side. Repeat the same process of opening and closing the Gatekeeper Rail Clip to attach it to the Rail Loops in your bigger bag. Slip the Cache inside the bigger bag, and pull it back out: you’ll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop from your bigger bag entirely while it is still encased in the protective Cache.
